Abstract
A method and a device for producing and/or conditioning powdered material. The inventive method is characterized in that the material is treated in several stages in a spouted bed comprising inert particles, wherein the powdered material that is preprocessed in a first spouted bed of a first jet chamber (6) and is separated from the larger material particles in an integrated dust collector is fed to a superimposed second spouted bed of a second jet chamber (8) as a material-gas flow along with the gas flow discharged from the first spouted bed in order to be further reduced in size and be conditioned. After separating the fine particles from the larger material particles in a dust collector that is integrated into the second stage, the fine particles are discharged from the two-stage spouted bed treatment along with the gas flow as a powdered material having very small particle diameters. The separated larger material particles are once again fed to the second spouted bed of the second jet chamber.; The device includes a spouted bed apparatus in which a jet chamber encompassing an integrated dust collector as well as a second superimposed jet chamber encompassing another integrated dust collector are disposed.
Description
Technical field
The present invention relates to a kind ofly be used to make and/or the method for conditioning of powdered material and the equipment that sets with it.
Background technology
The known shape material that in a fluidised material layer, makes powder is wherein imported an air-flow, to keep the material layer of fluidisation.What several kinds were used for moving the fluidised material layer below known here can be so as to making the basic mode of graininess or dusty material.
1. spray dryer
In the spray dryer that is for example known by Patent data DD 285724A5, in the high temperature gas flow that contains material, spray the liquid that contains solid.In air-flow, form material granule through drying, they have hollow ball shape or its fragment.The material granule that forms has bigger granularity, has poor emulsifiability more mostly.Spray dryer by prior art is very big with therefore expensive equipment, requires big repacking space and big energy requirement.These spray dryers are not suitable for making very little solid particle.The heat treatment that in spray dryer, can not add to the particle of making.
2. be with the fluid unit of inert bed
The fluid unit of for example being known by Patent data US 6187238 that has inert bed (Inertbetten) has a ventilative fluid bed bottom surface.Gas through from following input forms a fluidised material layer through the fluid bed bottom surface, also has corresponding inert body (Inertkoerper) in its inside.Yet can not make the very thin particle below about 100 μ m with them; Because the pulse that acts on the inert particle (Inertpartikel) only is decided by that inert particle is in the existence layer of fluid bed; That is the only main vertical upper and lower reciprocating motion between eddy current point and output point, therefore do not satisfy by evaporating/requirement of the solid particle that aerosolizable liquid manufacturing is thin.Solid in being included in adding liquid wherein can not carry out other heat treatments in the fluid bed stage the lip-deep drying of inert body.
3. be with the atomizing scrubbing tower of fluid bed
For example by the known atomizing scrubbing tower of Patent data DD 272576A3, they in its lower end with a fluidisation bed operating.Here fluid bed can be used or without inert body work.Here can carry out subsequent heat treatment or mechanical treatment through the corresponding abrasion of the particle that falls from the atomizing scrubbing tower conditionally.Its shortcoming is that the mixing of different air-flows takes place when subsequent heat treatment.When this combination, also limited fine grain manufacturing for above-mentioned reasons.
4. jetted layers device
In the inert bed jetted layers stage; Be applied to pulse on the inert particle significantly greater than with in the fluid bed of identical inert body; Because in inlet zone endoparticle speed significantly greater than the output speed of (for example big 10 times) particle, and since the typical structure of spraying equipment however particle do not exported.By Patent data DD 225630A1, DD 224233A1, DE 10303836B4 become known for the making powder jetted layers device of shape material.Wherein import high velocity air from the below to the jetted layers device for the jetted layers that produces a vertical rotation.The liquid that contains solid for example through single, double or many materials jetting device from the below, top or side spray into the jet chamber like this, makes the wetting as far as possible all the time inert particle of liquid surface, that is do not exist and overflow.The liquid that contains solid, for example mud also can pass through suitable transport, for example screw rod and/or slurry dispenser, for example the wheel of rotation is transported on the inert bed of motion.Employing is positioned at shot-peening steel ball, Ceramic Balls or the Teflon particle of suitable particle size, shape, surface nature and the density of jetted layers as inert particle.Liquid is evaporated through high temperature gas flow, thereby forms on the one hand dry material granule and dry material on inert particle.Material granule is ground through the inert particle by rolling shape beam motion with dry solid, discharges from the jet chamber with the form (for example＜50 μ m) of dust.Dust is separated at the different solid separators (cyclone separator, filter) of the identical or different type of the single or plural serial stage that is arranged in the outside as product usually.Series multiple through at jetted layers device dust separator at the back can obtain the power of the more and more littler dust-like product-basis of particle size in inert bed-jetted layers stage.Shortcoming is that desirable little granularity can only be given birth to the volume production that can ignore little.The series connection consumes energy of dust separator is therefore very expensive in addition.

Roughly give the jet chamber 6 input air-flow or material air-flows 12 according to method of the present invention at the center; Give jet chamber's 8 input materials-air-flow 15; And to the such deflection of jetted layers device 1 lateral wall, 3 directions, thereby obtain one along jet chamber 6 and 8 axial rolling shapes, on lateral wall 3 towards flow 13.Find, the inert bed that rolling shape ground moves upward along the lateral wall 3 that tilts when this injection guiding grind effect than much bigger when the injection guiding from outside to inside.In jet chamber 6 and 8, form a jetted layers 4 through air-flow, it is by material granule, inert body with by forming attached to the material granule wet and that do on the inert body.13 make material granule and inert body upwards get rid of apace and come back to gas input port according to the direction of arrow 14 through flowing of making progress along the madial wall of built-in fitting 5 inclinations along the lateral wall 3 that tilts; And upwards get rid of again, thereby form the rolling form that inert particle flows.Sometimes can demonstrate rapid reciprocating stratum granulosum through rolling.This particle circulation is carried out very fastly and is steady.
Can give the jetted layers 4 input liquid in jet chamber 6 and/or the jet chamber 8 or contain the liquid of solid through jetting device 10, like suspension, solution, liquation or mud.
Above jet chamber 6, carry out material separation, preventing from the jet chamber 6 the too big dust granules of first jetted layers, 4 outputs, and they are imported in first jetted layers 4 again downwards through dust separator 7.The size of dust separator 7 is definite like this, make it not only can let desired dimensions powder particle but also the dust granules with bigger slightly sizes is passed through, but no longer include too big particle.Too big dust granules falls into the jetted layers 4 of jet chamber 6 again, and continues there to pulverize and upwards output again.
Import the jet chamber 8 that be positioned at its top with air-flow as material-air-flow 15 through the material granule of dust separator 7.In jet chamber 8, rebulid a jetted layers 4, but its adapts to the condition changed.Jetted layers 4 is equipped with such inert body, and they have the for example less and/or lighter inert body with rough surface under the similar situation of layer quality.In the rolling shape jetted layers 4 of jet chamber 8, also too big particle continues to be pulverized, and the dust granules that has target size then and passes the dust separator 9 that is arranged on 8 tops, jet chamber together, and it is designed to only also let the particle of target size pass through.Still too big dust granules falls to get back in the jet chamber 8 from dust separator 9, and continues to grind forr a short time.
In jet chamber 6 and 8, mainly infinitely carry out the device interior precise dose and regulate, also be used for material hot treatment sometimes through the common heating generator with 30kHz-300MHz frequency range 11 according to the present invention.Heater 11 is arranged in the built-in fitting 5.Material and inert body on its lateral wall with material closely and little speed to lower slider; Make exist here on the one hand through from built-in fitting 5 by of the heat conduction of the wooden partition surface of eddy-current heating to the inert particle of the wet coating that is not dielectrically heated, but especially by heating generator 11 induction ground directly to the heat conducting particularly advantageous condition of the inert particle of the coating that wets.
If the enough ohm conductive capabilities of wet product-wet dust, the liquid that sprays into or the mud that feeds-on the inert body surface, have; Thereby can in electric field, promote heating through ionic conduction, are particularly advantageous conditions for adopting thermatron 11 so.If for example in the solid of water-wet, comprise the salt of dissolving, just conductive capability is enough high so.Because conductive capability itself depends on water capacity in this solid, wet zone is stronger than dry zone heating, and this caters to the solution of being asked a question very much.That is to say; The soft rising of this heating generator 11 temperature or both acted on reposefully sometimes on the sidewall of built-in fitting 5 of wet coating; Especially act on again on strenuous exercise and the fully mixed jetted layers, if inert body by a kind of be suitable for that material that high frequency conducts heat is formed and with wet more or less, treat the milled solid grain coating.So just, guarantee to coating or not coating inert body and thus to pending product fast, effectively and accurate heat transmit.
In order in low temperature range, to adjust temperature, can replace heating generator from the 2nd grade of 8 jetted layers through constituting hollow built-in fitting 5 direct direct cooled gas or cooling fluids.
In addition, can carry refrigerating gas for second level jetted layers 8 through a gas inlet pipe 17 from same purpose.
